A familiar light shines in the east at dusk, Venus makes a pit stop at a departing star cluster, and Comet PanSTARRS (C/2016 M1) coaxes before dawn.
This week Venus shines in the west during twilight. Jupiter glares in the southeast at nightfall, and Mars and Saturn rise late at night.
Jupiter's at opposition this week. Close and bright, it shines like a midnight version of Venus. No matter your scope, the biggest planet is always a crowd-pleaser.
Want to become a better astronomer? Learn your way around the constellations! They're the key to locating everything fainter and deeper to hunt with binoculars or a telescope.
Time travel is one of the best things about astronomy. Check out two websites that give skywatchers a more visceral sense of stellar distances and how constellations change shape across the sweep of time.
In a rare move, a sleepy cataclysmic variable blows its top and suddenly becomes a nova.
This month's astronomy podcast tells you how to use Venus and the Big Dipper to find many bright stars and constellations. Meanwhile, Jupiter lurks low in the east after darkness falls.
Keep an eye on the changing pattern of Venus with Aldebaran and the Pleiades, in the west as twilight fades.
Come along for a 7-night tour of some of the Moon's most compelling features visible in small telescopes.
Friday, April 20 • This evening the dark limb of the crescent Moon will occult 4th-magnitude multiple star Nu Geminorum, in the feet of Gemini, for parts of the southern U.S. and points south. For rough time estimates at your location, interpolate between the time predictions in the April Sky & Telescope, page 48. Saturday,…
The annual Lyrid meteor shower will shoot off silent fireworks on Earth Day this Sunday. We explore the shower's origin and how best to view and photograph it.
Looking for something to do on Saturday? Make plans to celebrate Astronomy Day on April 21st!
After dark, Leo walks horizontally across the meridian high in the south. His brightest star is Regulus, the bottom star of Leo's Sickle.
Here's an opportunity for amateur astronomers to reveal more about asteroid Amalthea's satellite.
Stare up at the Milky Way band on a dark night and you'll see missing pieces from clouds of foreground dust that absorb the light of distant stars. There are other mottled "milky ways" just like ours, millions of light-years away.
The sky's been bursting with exploding stars this season. Plus there's a new storm on Saturn. What's a skywatcher to do? Haul out the scope!
The two Dog Stars stand vertically aligned around the end of twilight. Look southwest. Brilliant Sirius in Canis Major is below; Procyon in Canis Minor is high above.
We lift the Lion's paw to find a bright, red variable star, a germinating planetary nebula, galaxies rarely visited, and a diversity of doubles.
After nightfall, Orion is still well up in the southwest in his spring orientation: striding down to the right, with his belt horizontal. Shining above the belt is bright orange Betelgeuse. Down below the belt is bright white Rigel.
This month's astronomy podcast guides you around the nighttime sky during April, giving you easy-to-follow help for finding bright planets and key stars after the Sun goes down.
Southern Hemisphere objects like Omega Centauri and the Magellanic Clouds make Northern Hemisphere observers envious. Today, we turn the tables and find out what those living in negative latitudes would love to see up north.
China's premier space station, Tiangong 1, has a one-way ticket into the Earth's atmosphere later this month. See it before it's no more.
The first-quarter Moon shines high above Orion on the evening of March 24, 2018, in the feet of Gemini below Castor and Pollux.
Stars are time machines that can transport us into the past or future. They can also illuminate our own personal journeys, as Arcturus did for me one night.
Watch the low in the east-northeast for the rise of the "Spring Star," Arcturus. Find the Big Dipper high in the northeast and follow the curve of its handle far around and down to see where Arcturus will be.
